Purpose: The purpose of this study was to explore the relationship between milk intake and prevalence rates of chronic diseases using KNHANES data, and the significance of the relationship was tested based on meditators, socioeconomic status (income, education), dietary behaviors (smoking, alcohol drinking, breakfast, and eating out), and physical activity (walking, medium, and high). Methods: Using the 5th and 6th survey data of KNHANES, milk intake rates and presence of seven chronic diseases were summarized and analyzed by ANOVA for two groups of adult men and women as follows: hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, abdominal obesity, obesity, and metabolic syndrome. The dependent variables for the presence of seven chronic diseases regressed with socioeconomic, dietary behavior, and physical activity variables according to Logistic models. The dependent variables for milk intake using predictor variables of socioeconomic, dietary behaviors and physical activity were analyzed according to Logistic models. Finally, the significant socioeconomic, dietary behavior, and physical activity variables in the above model along with milk intake as a control variable or mediator variable regressed with significant chronic diseases according to Logistic models. Results: Milk intake, socioeconomic status, dietary behaviors, and physical activity were significantly different among the two groups of adult men and women, which were also critical factors to the prevalence of chronic diseases. The dependent variable for prevalence of chronic diseases regressed with significant factors of socioeconomic status, dietary behavior, and physical activity variables according to chronic diseases using the control or mediator variable of milk intake and summarized as follows: For adult men, milk intake controlled the education effect on diabetes partly, alcohol on hypertension and hypertriglyceridemia, low HDL-cholesterol, metabolic syndrome, breakfast on metabolic syndrome, eating out on obesity, and medium physical activity on hypertriglyceridemia. For adult women, household income on hypertriglyceridemia, diabetes, abdominal obesity, education level on hypertension, alcohol drinking, eating out, and walking activity on abdominal obesity, alcohol, breakfast, eating out, walking activity on low HDL-cholesterol, and medium physical activity on hypertriglyceridemia and low HDL-cholesterol were partly controlled by milk intake. Other significant socioeconomic status, dietary behavior, and physical activity variables related to prevalence of chronic diseases were fully controlled or mediated by milk intake. Conclusion: This study shows that milk intake (daily more than 200 g) prevents chronic diseases such as hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, obesity, abdominal obesity, and metabolic syndrome.

This study was conducted to analyze the relationship between the practice of aerobic exercise and the prevalence and risk of arthritis with comorbid chronic diseases. For this study, the National Health and Nutrition Examination Survey 2017-2019 data were used and 17,356 people were selected as subjects. The relationship between the practice of aerobic exercise and the prevalence and risk of arthritis according to demographic characteristics and chronic diseases was analyzed by the chi-square independence test and Breslow-Day test. While the rate of aerobic exercise was low among women, the elderly, the low-income group, the low-education group, and people living in rural areas, the prevalence and risk of arthritis were relatively high. And in the chronic disease-positive group, those who practiced aerobic exercise had a relatively lower prevalence and risk of arthritis than those who did not. In particular, the practice of aerobic exercise was an effective complement in reducing the prevalence and risk of arthritis in people with high blood pressure, diabetes, and dyslipidemia. Therefore, the practice of aerobic exercise such as walking, slow running, and aerobic dance should be recommended in terms of the preventive medicine and health care to people who are in the group with a high prevalence of arthritis in demographic characteristics and people who have comorbid chronic diseases.

This study was conducted to empirically analyze the prevalence and risk of chronic diseases in the family history of chronic diseases using data from the Korea National Health and Nutrition Examination Survey 2019. Based on 5,691 people, after controlling for socio-demographic variables that were related to family history of chronic diseases, logistic regression analysis was performed to verify the odds ratio, which was the risk of family history of chronic diseases for the prevalence of chronic diseases. The main results were founded that Odds ratio, which was the risk of chronic diseases in groups with a family history compared to those without a family history, was statistically significant at hypertension(2.623), dyslipidemia(1.868), diabetes(1.964), and arthritis(1.435) when gender, age, income status, education level and residence were controlled. These results suggest that it is not only necessary to develop a standardization tool for family history tests, but also a health and disease management system for members with a family history in terms of preventive medicine in health care. This study is significant in that it proposed a practical plan in terms of health care by controlling variables that affect the prevalence of chronic diseases and empirically identifying the risk of family history of chronic diseases.

This study determines the difference in prevalence of anemia and hemoglobin concentration between chronic obstructive pulmonary disease (COPD) and control groups in the elderly. Moreover, this study also examines the prevalence of anemia and hemoglobin concentration according to the severity of COPD in the elderly. Medical records of 8150 participants who answered the 7th National Health and Nutritional Survey conducted in 2016 were reviewed, and a total of 694 participants was included in the analysis. Participants were classified into two groups: COPD and control groups. Laboratory studies on hemoglobin, hematocrit, red blood cell concentration and prevalence of anemia were collected. Subgroup analysis was also conducted according to the severity of COPD. No significant differences were determined for the prevalence of anemia and hemoglobin concentration between both groups. Hemoglobin concentration was significantly higher in the COPD group. Although not statistically significant, there was a tendency for decrease in the prevalence of anemia and increase in the hemoglobin concentration as the severity of COPD increased. Our findings present specific data about the prevalence of anemia and hemoglobin concentration in elderly patients with COPD. Hence, we propose that occurrence of anemia in elderly patients with COPD requires further evaluation of the causes.

Objectives: This study was conducted to identify the relations between multiple chronic diseases and peridontal diseases in Korean adults. Methods: A total of 4,142 cases was set for analysis, who aged 35 and over and finished with the third year health survey and oral health check-up of the fifth Korea National Health and Nutrition Examination Survey(2012). Peridontal disease was defined if community periodontal index(CPI) was 3(formation of paradental cyst of more than 4mm) or 4(formation of paradental cyst of more than 6mm). Results: The subjects consisted of 48.5% male and 51.5% female. The prevalence rate of peridontal disease was found to be 30.1% in total. In peridontal disease the more the age increased, and the lower the education level and income level as well as the more where the residential area was rural, the higher the prevalence rate was(p<0.01). According to the number of multiple chronic conditions the prevalence rate of periodontal disease accounted for 27.8%, 31.9%, 33.1%, and 35.2% when there were 0, 1, 2, and 3 or more chronic diseases respectively. As a result of logistic regression analysis, gender, age, education level, residential area, current smoking, and use of oral hygienic products were found to be significant factors on peridontal disease. Conclusions: This research revealed the prevalence rate of peridontal disease was 30.1% in Korean adults and health behaviors affecting on periodontal disease were more significant.

Purpose: The aim of this study was to investigate the current prevalence of protein-energy malnutrition (PEM) and the nutritional status of hospitalized pediatric patients. Methods: We evaluated the nutritional status of the 200 patients from February to July 1994 and the 233 patients from February to July 1999 admitted to Pediatric Department of Chosun University Hospital. Nutritional status was assessed by anthropometric and laboratory data. The nutritional status was classified according to based on the Waterlow criteria and using the laboratory data obtained between 3 days to 5 days after admission. Results: 1) The prevalence of acute PEM (weight for height) was as follows: severe, 0.5%; moderate, 7%; mild, 18%; and none, 74.5% in 1994 and severe, 2.24%; moderate, 3.59%; mild, 19.73%; and none, 74.4% in 1999. 2) The prevalence of chronic PEM (height for age) was as follows: severe, 5%; moderate, 5.5%; mild, 25.5%; and none, 64% in 1994 and severe, 2.24%; moderate, 4.04%; mild, 22.87%; and none, 70.85% in 1999. There was not a statistically significant difference between 1994 and 1999. 3) The prevalence of PEM according to age group, all age group had in general higher prevalence of mild PEM. 4) Values for hemoglobin and albumin were below than total lymphocyte values in PEM. Conclusion: The prevalence of acute or chronic PEM was common in hospitalized children. Therefore, the assessment of nutritional status may an important role to establish effective nutritional support and to improve their subsequent hospital course in hospitalized pediatric patient.

Objective: Despite the increasing number of female participation in employment, blue-collar women have been exposed to higher health risk. This study is to describe the prevalence of chronic diseases, health behaviors, and medical service utilization of female blue-collar workers. Methods: Data were derived from the 2001 Korea National Health and Nutrition Survey (KNHANES). The sample was made up of 37,108 male and female participants aged 20 or over selected nation-wide by probability sampling from Korea. This study applied the logistic regression for nominal variables such as disease prevalence and health behaviors and with the regression for continuos variables such as the length and costs of medical services. Results: In general, women's prevalence of chronic illness and uncured rate were significantly higher than male, and especially female blue-collar workers had the highest prevalence, uncured rate, unhealthy status, and perceived stress. However, the medical care cost was the lowest in female blue-collar workers. Conclusions: The findings suggest that female blue-collar workers were more likely to experience health problems, and that despite the highest health risk, health service is not effectively utilized, and health policy maker should take consider of special status of female blue collar workers who are in health inequality.

고혈압과 당뇨병은 성인에서 흔히 볼 수 있는 만성 질환으로서 특히 두 가지 질환을 함께 가지고 있는 경우가 많다. 고혈압과 당뇨병은 둘 다 심장질환, 뇌혈관질환, 신장질환 및 망막질환의 위험 인자로서 조기에 합병증을 발생시켜 유병률과 사망률을 증가시킨다. 통계에 의하면 당뇨병을 가지고 있는 사람은 없는 사람에 비해서 두 배 이상 고혈압이 발생하고 당뇨병 환자의 1/3에서 결국 고혈압이 발생하는데 특히 50세 이전에는 여자보다 남자에서 많이 발생하며, 50세 이후에는 남자보다 여자에서 많이 발생한다. 또한 백인에서 보다 흑인에서 두 가지 병을 가지고 있는 경우가 두 배 이상 많으며 경제적으로 빈곤할 수록 많이 발생한다고 한다. 당뇨병 환자에서는 고혈압이 유병률이나 사망률을 증가시키는 가장 중요한 요인인데 그 이유는 고혈압의 합병증, 즉 관동맥질환, 뇌졸중, 말초혈관질환, 신장질환 등의 발생과 성인 시력장애의 가장 흔한 원인으로 인정되고 있기 때문이다. 또한 당뇨병 환자에서도 고혈압 발생이 두 배로 많은데 당뇨병의 유형 및 기간, 신장질환 유무, 연령, 성별 및 인종에 따라 관련이 있다고 한다. 두 가지 질병이 다 같이 유사한 합병증을 일으켜 표적 장기에 손상을 주므로 두 질환을 가지고 있으면 이러한 합병증의 발병을 더욱 앞당기게 된다.
